VELOCIPEDE.

SPECIFICATION forming part of Letters Patent No. 448,580, dated March17, 1891. Application filed September 1, 1890. Serial No. 363,623- (Nomodel.)

To all whom it may concern:

Be it known that I, WILLIAM EDWARD H UR- RELL, a subject of the Queen ofGreat Britain, residing at London, in the county of Middlesex, England,have invented certain new and useful Improvements in Velocipedes, ofwhich the following is a full and clear description.

llIy invention relates to an improved springfork for the steering-Wheelof a velocipede, and to an improved brake for use therewith, the objectbeing to reduce vibration arising from the steering-wheel, and to socom-pensate the brake-spoon lever that its action is not impaired by thejigging motion of the wheel relative to the main fork of the framecarrying it. I attain this end in the manner illustrated by theaccompanying drawings, in which-- Figure 1 is a broken View in sideelevation showing my improved spring-fork and compensated brake. Fig. 2is a perspective view of the spring-fork detached, and Fig. 3 is aperspective view of the brake-spoon lever detached.

Throughout these views similar parts are marked with the same letters ofreference.

Onto the end of each prong of the main fork A, adapted to carry thesteering-wheel B, is fulcrated a rocking lever O. The forward ends ofthese levers are adapted to carry the axle b of the steering-wheel.

To the rear ends of the levers C O is jointed a supplemental fork D, theprongs of which.

terminate in a crown d, from which extends a central stem d, adapted toslide through an eye in a bracket a, formed on -or fixed to the crown Aof the main fork.

On the stem (1 is placed a coiled or spiral spring E, acting between thebracket 0/ and a nut and washer (Z on the free end of the said stem. Itwill thus be seen that when the steering-wheel meets an obstacle on theroad it is allowed to rise, due to the rocking action of the levers G 0,controlled by the spring E, through the supplemental fork D.

The brake-spoon lever F, instead of being of the main fork, isbifurcated at its rear end and fulcrated to the prongs at the crown clof the supplemental fork D, and the point of connection of the operatingrod or plunger F is at such a position on the spoon-lever F as will giveit an equivalent movement to that of the rocking levers O C, so that thebrake-spoon 5 i is automatically compensated to the movement of thesteering-wheel, and always remains at one uniform distance from theperiphery thereof, whether the brake is on or off. It will thus be seenthat the jigging motion of the wheel is not transmitted to theoperating-rod or plunger F.

I wish it to be particularly understood that I do not limit myself tothe precise details of construction herein described and shown, but holdmyself at liberty to make such changes and alterations as fairly fallwithin the spirit and scope of my invention.

Having now particularly described my invention and in what manner thesameis carried to practical effect, what I claim is- 1. In a velocipede,the combination of a main fork having a rearwardlyextended bracket,levers fulcrated to the ends of the fork-prongs, an axle supported bythe forward ends of the levers, a wheel carried on the axle, asupplemental fork connected to the rear ends of said levers and providedwith a spring-controlled stem loosely engaging the rearwardly-extendedbracket on'said main fork, and a lever-controlled brake-spoon fulcratedto the supplemental fork, substantially as set forth.

2. In a velocipede, the combination of a main fork having arearwardly-extended bracket, levers fnlcrated to the ends of thefork-prongs, an axle supported by the forward ends of the levers, awheel carrieol on the axle, a supplemental fork connected to the rearends of said levers and provided 0 with a spring-controlled stem looselyengaging the rearwardly-extended bracket on said main fork, and alever-controlled-brake-spoon having a bifurcated rear end fulcrated tothe prongs of said supplemental fork, substantially as set forth.

In witness whereof I have hereunto set my hand in presence of'twowitnesses.

WILLIAM EDIVARD HURRELIJ.
